Abstract

The generation of wastewater becomes higher due to the large number of student and staff enrollment is a result of rapid development in KUiTTHO.. Currently some of the wastewater was treaten by using individual septic tank. Some of them collect more wastewater consequently increased the hydraulic and nutrients loading. This paper describes the study of effluent domestic wastewater treatment using sub-surface flow (SSF) constructed wetland. A model of 3 day retention time SSF constructed wetland was build, has gravel and planted with submerged vegetation, cattails (Typha angustifolia). However, studies on the suitability of these plants have been reported are very limited under tropical climate. This study was conducted to measures the effectiveness of SSF constructed wetland to treat the effluent domestic/septic tank wastewater. This study had focused in BOD5, COD and suspended solids. The results showed that SSF constructed wetland has a potential in polishing high strength effluent domestic/septic tank wastewater. The proposed area was depends on the pollutant removal percentage, the big area is needed for higher removal. The area of 56 m2, 31 m2 and 28 m3 approximately are required each for SS, BOD5 and COD removal respectively.
